BUNK-CAR.

SPECIFICATION forming part of Letters Patent NO. 582,217, dated May l1,1897'.

Application filed February 27, 1896. Serial No. 581,028. (No model.)

To all whom it may concern:

Be it known thatI, HORACE J. MORTON, residing at Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Bunk-Cars for Lumber-Driers, of which the following,when taken in connection with the drawings accompanying and forming apart hereof, is a full and complete description sufficient to enablethose skilled in the art to which it pertains to understand, make, anduse the same.

The invention relates to bunk-cars ordinarily used for piling lumberthereon to be run into the dryingroom of a lumber-drier and the lumberthere seasoned while on such bunk-car and to be thereafter run out ofsuch drying-room with the lumber thereon and unloaded. Such bunk-carsare usually used in sets of two or three, the lumber when of shortlengths being supported at each end thereof on a bunk-car and when thelumber is of longer lengths a third bunk-car being placed underneath thecenter of the lumber.

The object of the invention is to obtain a bunk-car which can beconstructed entirely of metal, preferably of steel; to obtain abunkcarwhich shall be simple in construction, easily put together at the placeof erection of a lumber-drier or lumber-kiln when shipped thereto inpieces, strong and durable, and not liable to breakage or to get out ofadjustment or repair.

A further object of the invention is to obtain bunk-ears which whenloaded can be easily moved into and out of the drying-room, togetherwith the load thereon; and a still further object of the invention is toobtain a car which shall be lower than the bunk-cars now and heretoforein general use, whereby a greater number of courses of lumber can bepiled thereon and gotten into a dryingroom of a given height thanheretofore.

In the drawings referred to and forming a part hereof, Figure l is aside elevation of a bunk-car embodying my invention; Fig. 2, a top planview of such car; Fig. 3, a vertical sectional view on line 3 3 of Fig.l, viewed in the direction indicated by the arrows; and Fig. 4, avertical sectional view ou line 4 4 of Fig. 1, viewed in the directionindicated by the arrows.

A reference-letter applied to a given part is used to designate suchpart throughout the several gures of the drawings wherever the sameappears. v

A A are steel channel-irons, usually termed channels, connected togetherby spreaders or separators B B B andsupported or mounted on wheels D D.Y Y Y The several spreaders or separators B B B are duplicates and eachone thereof is constructed and secured in place between the channels AA', as follows:

b is the rim of the spreader or separator, usually and preferablycircular in cross-section g b', the web thereof, and b2 the hub. The hubZ22 is of slightly-greater length than the width of rim h--that is, thehub b2 extends a short distance beyond the edgeof the rim l), as is wellillustrated in Fig. 3 of the drawings, so that such extension of the hubshall enter the holes a a', respectively, in the web of channels A A.

b3 b3 are the extensions of hub b2, and it will be observed that suchextensions are not of sufficient length beyond the edge of rim b toextend through the web of the channels A Af-that is, the thickness ofthe webs of the channels A A', respectively, is greater than theextensions b3 b3 beyond the edges of rim b.

h4 is a hole through hub h2, through which hole, as well as throughholes ct a in channelirons A A', respectively, the bolt b5 extends. Boltb5 has head h6 at one end thereof, nut bVT on the other end, and washersbs 198, adjacent to the web of the channels A A.

When the several parts constituting the spreader or separator B areassembled in place, as illustrated in Fig. 3 of the drawings, the nut D7is screwed up against the washer 198, adjacent thereto, so that suchwasher, as well as the washer bs, adjacent to the head lf, shall bebrought against the web of the channel adjacent thereto sufficiently tospring the webs of the channel inwardthat is, to bow them inwardly, (theamount of such spring being determined by the character of the steelforming the channels,) and thereby such webs exert a tensile strain onthe bolts b5. The loosening of the nut 117 from the bolt b5 is therebyprevented, the washers hs bs being forced against the head h6 and nut127, respectively.

ICO

lVheel D is constructed and mounted in place between the channels A A inthe following manner:

E is a stationary axle mounted between the webs of channels A A. Tobring the axle E down as low as possible in the channels A A', as wellas to insure the rigidity and non-1o tatabilityv of such axles, aportion thereof isremoved at each end, forming shoulders e e,arranged,respectively,to come in contact with the inner faces of thechannels A A', adjacent thereto, opposite the lower flange of suchchannels, and the horizontal faces e e', coming in contact with acorresponding face in the hole through the web of the channels,respectively.

F F are rollers in the hole in hub cl2, extending around the axle E.(See Fig. 4.)

Wheel D has the flan ged rim d, web d', and hub d2.

G G are washers, which are preferabl)T rotatably mouu ted on the axle Eat the ends of the hub d2 of wheel D. lVashers G G are designed to keepthe rollers F F in place in the hub d2 and also to prevent friction inthe rotation of wheel D and rollers by presenting to the ends of therollers a rot-ating face or disk against which such ends shall abut,instead of the web of the channels,respectively.Y A further object ofthe washers is to present a surface or disk which shall extend below thelower dan ge of the channel-irons, respectively, and adjacent to theends of the rollers F F F to enable ine to set the axle E down, ashereinbefore stated, in the channels A A and so obtain a bunk-carwhereof the wheels are of the largest possible diameter as coinparcdwith the depth of the channels used, it

being considered essential that the flange of the wheel D shall not comeabove the upper edge or top of the channel, such upper edge or top ofthe channel forming the top of the bunk-car.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- Y l. A bunk-car consisting ofchannel-irons arranged as right and left, combined with spreadersextending between the channelirons and holding thein respectively inplace such spreaders having peripheral edges against which thechannel-irons are respectively forced by a bolt extending centrallythrough the spreader, and flanged wheels rotatably mounted between thechannelirons, such wheels consisting of a non-rotatable axle rigidlysecured between the channelirons, a dan ged wheel, rollers in the hub ofthe wheel and around the axle, and washers rotatably mounted on the axleat the ends of the hubs; substantially as described.

2. A bunlccar consisting of channel-irons arranged as right and left,spreaders extending between the channel-irons and holding them rigidlyin place, axles having shoulders on the ends thereof extending betweenthe channel-irons and held rigidly in place, a flanged wheel around theaxle, rollers in the hub of the wheel and around such axle,and washersmounted on the axle against which the ends of the rollers abut;substantially as described.
